We need to be much more robust about the google chart packages getting loaded

[rickmcgeer]

There are timing issues here -- errors are thrown when we attempt to draw a Google chart before the visualization libraries are loaded. This needs to (a) be checked; and (b) ensure that the gViz libraries are loaded in an await block.

Added if (!this.gViz) return; to DashboardCommon.drawChart
